Dell DW5811e / Sierra Wireless EM7455 WWAN Not Working
influenist replied to Nancy10's topic in Modems/WWAN modules
Hey @miki991 , I tried all sorts of combinations yet can't remember exactly though if I followed up your notes. Even made the kext working for the 3 variants. I'll retry this at some later stage as I'm too caught up with work / private life. Why not buy the card and help the community ?! Attached the latest version I could find in my backedup EFIs.

Dell DW5811e / Sierra Wireless EM7455 WWAN Not Working
influenist replied to Nancy10's topic in Modems/WWAN modules
While the EM7430 works with my kext. (I guess the product ID needs to be adjusted still). The EM7455 seems not. What I did: Wrote the kext for DW5811e / EM7411 according to the correct PID & VID attached above. Which after it appears on WANN section (location id show xxxxxxxx / 0 as others also have in their screen). Then with the correct APN the error shows: So I updated the firmware and all config settings using LIVE UBUNTU CD 18.04 with: https://github.com/danielewood/sierra-wireless-modems His autoscript is perfect for updating FW, configuring the whole card according to our needs & sets the PID/VID to generic to bypass any vendor locks. Whilst I updated the kext to reflect all MC/EM7455 cards PID/VID (Lenovo / DELL / Generic). Still the error "Network Connection ... " shows. Please also see the location difference: NOTE the firmware: SWI9X30C_02.08.02.00 r5428 CARMD-EV-FRMWR2 2016/01/06 20:38:53 While at!priid? shows the updated firmware: SWI9X30C_02.33.03.00_00_00_GENRIC So I manually check the connection using COM port: screen /dev/tty.wwan 115200 screen /dev/tty.wwan 115200 Which after I'm able to manually connect using at commands. Any ideas where to look? Perhaps it is the interface mapping? <key>InterfaceMapping</key> <dict> <key>0</key> <dict> <key>name</key> <string>wwanDM</string> </dict> <key>2</key> <dict> <key>name</key> <string>wwanGPS</string> </dict> <key>3</key> <dict> <key>name</key> <string>wwan</string> </dict> </dict> -
